Description
本発明は、中性子散乱実験用部材及びその製造方法に関する。 The present invention relates to a member for neutron scattering experiment and a method for manufacturing the same.
物質の結晶構造を測定する方法として、中性子回折法とＸ線回折法がある。このうち、中性子回折法はＸ線回折法と比較して水素、リチウム、酸素等の軽元素を高精度で測定できることから、近年注目されている。 As a method for measuring the crystal structure of a substance, there are a neutron diffraction method and an X-ray diffraction method. Among these, the neutron diffraction method has attracted attention in recent years because it can measure light elements such as hydrogen, lithium, and oxygen with higher accuracy than the X-ray diffraction method.
中性子回折法は、中性子を被測定試料に放射し、被測定試料により散乱される中性子の量を検知することにより行われる。 The neutron diffraction method is performed by emitting neutrons to a sample to be measured and detecting the amount of neutrons scattered by the sample to be measured.
中性子回折法では、被測定試料は試料ホルダーの中に保持されているため、中性子は試料ホルダーを通過して被測定試料に到達する。そのため、試料ホルダーが中性子を吸収する場合には、測定結果から得られる中性子回折プロファイルに大きなバックグランド（ノイズ）が生じて測定精度が低下する。従って、試料ホルダーの特性として中性子を吸収しないことが必要である。 In the neutron diffraction method, since the sample to be measured is held in the sample holder, neutrons pass through the sample holder and reach the sample to be measured. Therefore, when the sample holder absorbs neutrons, a large background (noise) is generated in the neutron diffraction profile obtained from the measurement result, and the measurement accuracy is lowered. Therefore, it is necessary not to absorb neutrons as a characteristic of the sample holder.
また、中性子が試料ホルダー通過時にホルダー内で回折又は干渉すると、中性子回折プロファイルにブラッグピーク(Bragg peak)が生じる。このピークも被測定試料に無関係のピークであるため、測定精度が低下する原因となる。従って、試料ホルダーは、回折及び干渉が生じにくい特性も必要である。 Further, when neutrons are diffracted or interfered in the holder when passing through the sample holder, a Bragg peak is generated in the neutron diffraction profile. Since this peak is also a peak unrelated to the sample to be measured, it causes a decrease in measurement accuracy. Therefore, the sample holder also needs to have a characteristic that hardly causes diffraction and interference.
現在、中性子回折プロファイルにおけるバックグランドが少なく且つブラッグピークの発現が小さい金属としてバナジウム金属単体が知られており、これを用いて試料ホルダーが作製されている（例えば、特許文献１）。 At present, vanadium metal alone is known as a metal with a small background in the neutron diffraction profile and a small expression of the Bragg peak, and a sample holder is manufactured using this (for example, Patent Document 1).
しかしながら、バナジウム金属単体を用いても依然としてブラッグピークは生じるため、ブラッグピークを更に低減して測定精度を向上させることが望まれている。
本発明は、ブラッグピークの発現を低減させた中性子散乱実験用部材及びその製造方法を提供することを目的とする。 An object of the present invention is to provide a member for a neutron scattering experiment in which the expression of the Bragg peak is reduced and a method for producing the member.

The present inventors have found that it can be easily formed and have completed the present invention.

中性子散乱実験装置とは、中性子を放射し、被測定物の結晶構造や磁気構造を測定するものである。このような中性子散乱実験装置としては、例えば、日本原子力研究開発機構のJRR-3 HRPD、高エネルギー加速器研究機構のKENS VEGA等が挙げられる。 A neutron scattering experimental device emits neutrons and measures the crystal structure and magnetic structure of the object to be measured. Examples of such a neutron scattering experimental apparatus include JRR-3 HRPD of Japan Atomic Energy Agency and KENS VEGA of High Energy Accelerator Research Organization.

2. Method for Producing Neutron Scattering Experimental Member The method for producing a neutron scattering experimental member of the present invention includes 2.8 to 12.8% by weight of at least one metal selected from the group consisting of aluminum, chromium, iron and nickel, and A step of rolling a vanadium alloy composed of 87.2 to 97.2% by weight of vanadium. Since the manufacturing method of the present invention uses the vanadium alloy, it is excellent in formability. Therefore, the vanadium alloy can be uniformly rolled without generating undulation or the like, and as a result, it can be easily formed into a thin neutron scattering experimental member such as a sample holder or window material.
本発明の製造方法で使用するバナジウム合金は、金属単体としてアルミニウム、クロム、鉄及びニッケルからなる群から選択される少なくとも１種の金属を２．８〜１２．８重量％、並びにバナジウム金属単体を８７．２〜９７．２重量％を配合する限り限定されない。なお、各金属の組み合わせの好ましい配合量は上記中性子回折装置用部材で説明したものと同様である。このようなバナジウム合金の製造方法としては、例えば、アーク溶解法、真空誘導溶解法、エレクトロンビーム溶解法等が挙げられる。本発明では、特にアーク溶解法が好ましい。これにより、ボタン型等の塊状、板状、インゴット状等のバナジウム合金が得られる。 The vanadium alloy used in the production method of the present invention contains 2.8 to 12.8% by weight of at least one metal selected from the group consisting of aluminum, chromium, iron and nickel as a simple metal, and a vanadium simple substance. It is not limited as long as 87.2 to 97.2% by weight is blended. In addition, the preferable compounding quantity of the combination of each metal is the same as that of what was demonstrated by the said member for neutron diffraction apparatuses. Examples of the method for producing such a vanadium alloy include an arc melting method, a vacuum induction melting method, and an electron beam melting method. In the present invention, the arc melting method is particularly preferable. Thereby, vanadium alloys, such as a button-shaped lump shape, plate shape, and ingot shape, are obtained.
圧延方法は、上記バナジウム合金を使用する限り限定でなく、常法に従って行えばよく、例えば、冷間圧延、温間圧延等が挙げられる。特に、本発明では冷間圧延が好ましい。 The rolling method is not limited as long as the vanadium alloy is used, and may be performed according to a conventional method, and examples thereof include cold rolling and warm rolling. In particular, cold rolling is preferred in the present invention.
必要に応じて、圧延工程の前後又は圧延工程中に、焼鈍処理を１回又は複数回行ってもよい。これにより、うねりをより確実に抑制することができる。 If necessary, the annealing treatment may be performed once or a plurality of times before or after the rolling process or during the rolling process. Thereby, a wave | undulation can be suppressed more reliably.
焼鈍（加熱）温度は限定的でなく、通常８００〜１２００℃程度、好ましくは９００〜１１００℃程度とすればよく、焼鈍時間は、通常０．５〜３．０時間程度、好ましくは１．０〜２．０時間程度とすればよい。 The annealing (heating) temperature is not limited and is usually about 800 to 1200 ° C., preferably about 900 to 1100 ° C. The annealing time is usually about 0.5 to 3.0 hours, preferably 1.0. It may be about 2.0 hours.
焼鈍は、例えば、減圧下又は真空下で行えばよく、例えば、１０−３Ｐａ以下（特に１０−４Ｐａ以下）で行うことが好ましい。 The annealing may be performed, for example, under reduced pressure or under vacuum, and is preferably performed at, for example, 10 −3 Pa or less (particularly 10 −4 Pa or less).
本発明の中性子散乱実験用部材によれば、特定の組成の合金を使用しているため、中性子回折法を用いた測定により得られるプロファイルにおいてブラッグピークの発現をより低減させることができる。 According to the neutron scattering experimental member of the present invention, since an alloy having a specific composition is used, the expression of the Bragg peak can be further reduced in the profile obtained by the measurement using the neutron diffraction method.
本発明の製造方法によれば、特定の組成の合金を使用しているため、バナジウム合金にうねり等を発生させずに均一に圧延することが可能であり、その結果、試料ホルダー、窓材等といった肉厚の薄い中性子散乱実験用部材を容易に成形することができる。 According to the manufacturing method of the present invention, since an alloy having a specific composition is used, it is possible to uniformly roll the vanadium alloy without generating undulation or the like. As a result, the sample holder, the window material, etc. Such a thin neutron scattering experimental member can be easily formed.

Next, a plurality of the obtained small button type vanadium alloys were mixed and melted together at a melting output of about 16 kW to obtain an evenly alloyed large button type vanadium alloy material. The melting operation was performed using an oil diffusion pump and then replaced with high-purity argon gas so that oxygen and nitrogen gas components did not rise during melting.

The vanadium alloy materials for neutron scattering experiments of Examples 1 to 4 and Comparative Examples 1 to 4 obtained above were cut into plate-like vanadium alloys each having a width of 23 mm, a length of 23 mm, and a height of 5 mm.
次に、得られた板状バナジウム合金に真空熱処理炉を用いて焼鈍処理を施した。焼鈍条件は、真空度5×10-4Pa以下、焼鈍温度900℃、焼鈍時間１時間とした。 Next, the obtained plate-like vanadium alloy was annealed using a vacuum heat treatment furnace.

A member was manufactured. In addition, in the case of cold rolling, when the test piece was 1 mm in height and 0.3 mm in height, the annealing process (annealing conditions are the same as the above-mentioned) was given.

The obtained members for neutron scattering experiments of Examples 1 to 4 and Comparative Examples 1 to 4 were evaluated as follows. The evaluation results are also shown in Table 1.
A: Rolling with a height of 0.05 mm was achieved. B: Waviness occurred during rolling with a height of 0.05 mm. Δ: Waviness occurred during rolling with a height of 0.1 mm.
Test example (neutron diffraction measurement)
The vanadium alloys for neutron scattering experiments of Examples 1 to 4 and the vanadium metal for neutron scattering experiments of Comparative Example 1 were cut into a plate-like vanadium alloy (or plate-like vanadium) having a width of 23 × length of 23 × height of 5 mm. Neutron diffraction measurement was performed on this plate-like vanadium alloy. Table 1 shows the results obtained by plotting the diffraction intensity of the (110) plane, which is the strongest line of V, with respect to the lattice spacing d and evaluating the presence or absence of the Bragg peak.
図１から明らかなように、比較例１の板状バナジウム金属単体には、ブラッグピークと呼ばれる鋭いピークが生じていたが、本実施例１〜４のバナジウム合金材料には、ブラッグピークは見られなかった。従って、本実施例１〜４のバナジウム合金材料から得られる中性子散乱実験用部材にも、ブラッグピークが見られないことが分かる。 As is clear from FIG. 1, the plate-like vanadium metal of Comparative Example 1 had a sharp peak called a Bragg peak, but the Bragg peak was found in the vanadium alloy materials of Examples 1 to 4. There wasn't. Therefore, it can be seen that no Bragg peak is observed in the members for neutron scattering experiments obtained from the vanadium alloy materials of Examples 1 to 4.
